Application filed September 2, 1915.' Serial No. 4l81,53(i.'A

To all whom-it may concern: i i' Be it known that I, lJOHN F. OConNoin a v citizen of the United States, residing at Chi-` v cago, in thecounty of Cook and State of- Illinois, have invented a certain new anc useful 4Improvement in Draft-Rigging Yokes, of which the following is afull, clear, concise, and exactdescription, reference loe- 'inv had to the accompanying drawings,

D formirg a part of this specification.

This invention relatesjto improvements in draft rigging yokes.

In the present operation of railroad cars,

downward and the butt end upward. This causes excessive wear on the coupler shank in its-sliding movements over the carry-iron. The objectof my inventionis to provide a simple and efficient arrangement which will overcome the defects above indicated.

In the drawing forming -a part of the speciiication,'l4`igure l'is a longitudinalvertical sectional view of a car draft rigging i' Vshowing my improvements in connection therewith. And F ig. 2 is a horizontal sectional View of the structure shown in Fig. 1.

In said drawing, lO-lO denote the draft sills to which are secured the' rear stops 11 and front stops l2. Mounted between the sills is a shock absorbing device which I have indicated as of the friction gear-type at 13, the latter having associated therewith .a front' follower lei. The draw bar or coupler'l5 is shownas of standard type and is operatively connected with the shock absorbing mechanism by a Yoke designated generally by the reference A, to which it is connected by a coupler key 16, the latter eX- tending through and being slidable in slots 17in the draft sills.. The gear and yoke are supported by a saddle plate 1S. and the draw bar is upheld b v :i carry-iron 19.

The voke A@ is shown as of 4the two part type. although it will be understood the.

saine is merelyillustrative. V.As showinthe' yoke A comprises twopreferably:likemein- @TS @il-20, each 0f which basan upper-arm 2l, lower arm 29., rear connecting-portion 23,-

and av half hood at the forwardendfformed the forward ends of said arins 21.` Iand 2Q, and a side wall 24. The-side Walls Qlof the two members' 20-20 are provided with' slots 25 .to receive the coupler key, 16, said side walls being also siiitablyreinforced by ribs y The side walls 24: are forwardly eXA y tended as indicated at 27, said 'walls being preferably outwardly flared'fror'ri the coupler shank as clearly indicated in Fig. 2, to`

permit radial movements.

Each yoke member QO'alsolias an upperwall or flange' 28 and a lower wall or flange v Q9 extended forwardly. of the hood, lthe former having a curved portion 30 and a .horizontal portion 31, and the latter an i1p` wardly and outwardlycurved portion 321' and horizontal portion 33. s 'clearly indicated in the'drawing, the upper and lower flanges 28 and '29 overlap the upper and lower sides of the coupler'shank and are extended forwardly to a point preferably .slight-ly forward of the outer edge of the carry-iron 19 wlienthe parts are4 in normal position. From the preceding description, it will be seen that'the shank of the. couplerfis supported by the yoke between the points ,tzaf and does not come into contact' withthe carry-iron, and since, in the arrangement as shown no substantial' ainountof relative movement is provided for betweentlie coulpierand.' yoke, the 'coupler Ashank receivespractically no wear. On account of the eX* Itended support for the coupler shank, tendency of the coupler to tilt is prevented, eren.

when pulled out to the maximum extent 'unf Not only does ,the foregoing described are rangement materially increase the life of the coupler shank but the life A,of the carryironis also .increased since it is'not-subjectedto as severe wear asin those constructions where the couplerf is permitted to tilt and ride directly thereon.. .I claim: j
